Which welding method is better than the battery module?

Many known, power batteries are the core components of electric vehicles, and their performance directly affects the performance of electric vehicles. The power battery is now mainly used by lithium ion batteries, directly applied to the lithium battery module, and the lithium battery module refers to a combination of a lithium ion battery through a string and an external protective circuit housing. The welding technology and process of lithium battery modules is an important factor affecting the performance and safety of power cells. Domestic battery modules production standards are not uniform, and the welding methods are also different. Currently, there is electrical resistance welding, laser welding, ultrasonic welding, which mainly introduces the advantages and disadvantages of these three methods. 1, resistance welding Resistance welding is earlier in the market, the technology is mature, while the electrical resistant welding equipment has price advantages, but the disadvantage is that a large amount of heat is generated during welding, and it is easy to cause damage to the lithium battery, and it needs to be cleaned after welding. Unable to rework. 2, ultrasonic welding The advantage of ultrasonic welding is that no need to heat, it can detect whether the solder joint is firm and there is no need to clean after welding, but the disadvantage is that the welding surface cannot be polluted and the weldable material is limited. 3, laser welding The significant advantage of laser welding is that the welding speed is fast, the efficiency is high, the heat affected zone is small, and the workpiece is small, but the disadvantage is that the equipment is high. Chuyuan photoelectric is a professional manufacture of laser welding equipment. It has been successful in battery module welding, and customers can assist customers in equipment selection and process improvement, providing customers with a complete set of welding programs. The electric vehicle market has driven the rapid development of the lithium-industrial industry, and the lithium-e-equipment industry has also ushered in development. Battery module welding From a whole, laser welding has advantageous advantages, with high battery demand, the high efficiency of laser welding is high, which makes it more widely used in module welding applications, while laser welding technology is also In the gradual maturity, Chuyuan Photoelectric is actively cooperating with battery enterprises to develop battery welding automation programs, which has achieved remarkable results.
